One of the oldest buildings in Waterloo now has a new look.

The Paul Puncher menswear shop, which sells high-end clothing, has added a new wing to the 103-year-old Waterloo Train Station where it is housed.

The station has deep historical significance to Waterloo, as many local soldiers who fought in the First and Second World Wars started their journey overseas from its platform.

Company president Scott Puncher said the project took about one year to finish.

"I think getting it done has been the most exhilarating thing," he said Thursday at the opening of the new wing.

The Paul Puncher brand has been active in the region since 1919, when it first began under the name "Washburn Menswear" in downtown Kitchener. The store opened in the train station on May 1, 1997.

Waterloo Mayor Brenda Halloran said she’s pleased the building has been preserved over the years.

"We were very fortunate that we’ve been able to keep it so that future generations can see just the outside beauty of architecture from 100 years ago," said Halloran.

The project’s architect, Andrew Bousefield, told CBC News that the expansion was a long process since the building is a heritage structure, on a flood plane and near a railway line.

However, he says the finished product is a great example of the fusion of old and new design.

"You can be modern, and current, and still be respectful of history."
